TGS has begun its Northwest Shelf Renaissance 2-D seismic survey offshore Northwest Australia, aiming to provide “enhanced imaging through to the deeper stratigraphic section of the Dampier, Beagle and Bedout sub-basins and Exmouth Plateau.”

The survey consists of about 8,000 km (4,971 miles) of long offset, broadband 2-D seismic data along with magnetic and gravity data, TGS said. BGP will provide the BGP Explorer seismic vessel for the job.

“This new long offset 2-D survey will tie recent and deep wells with TGS’s existing 3-D coverage in the Exmouth Plateau, Carnarvon Basin,” TGS CEO Kristian Johansen said in a prepared statement. “In addition, this modern 2-D survey traverses the proposed 2016 Australian Offshore Petroleum Exploration Acreage Release areas, which are expected to be released in July 2016. “

Fast-track data will be available in November. Prestack depth migration data become available in May 2016.
